Answer:54

Step-by-step explanation:Since we are trying to find the amount of fencing needed to surround an area, we need the perimeter.

The formula for perimeter is 2 ( L + W ) with L being length and W being width.

Let’s just plug it into the formula.

2 ( 15 + 12 )

2 ( 27 )

54

The perimeter of the area is 54 feet, so we need 54 feet of fencing.
